[0040] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0041] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0042] Plasma is an ionized gaseous substance composed of positive and negative ions generated by the ionization of atoms and atomic groups that have been deprived of some electrons. In the boronization process, the traditional feeding method is mainly to use borane gas or other borane solid particles to be sent into the vacuum chamber after high-temperature gasification. However, neutral gas is easily ionized when entering the vacuum chamber. After ionization, the charged neutral gas will be affected by the magnetic field and electric field and deviate, making it difficult to enter the plasma core wrapped by the closed magnetic surface, resulting in a low density of plasma in the core, which affects the efficiency of the fusion reaction.

[0043] In order to solve the above technical problems, boron powder injection has become a new feasible boronization feeding method. However, there are many problems in the existing injection methods. In the method of charging with gas, it is difficult for gas to enter the plasma core, and the feeding efficiency is low; in the method of high-pressure gas driving, part of the driving gas will enter the vacuum chamber while injecting the projectile, affecting the normal operation of the vacuum chamber. Therefore, how to improve the efficiency of material injection and ensure the normal progress of the fusion reaction is an urgent problem to be solved.

[0044] The material injection device and the fusion reaction system are described in detail below through specific embodiments:

[0045] Reference Figures 1 to 10 As shown, some embodiments of the present disclosure provide a material injection device, including a transmission component and an injection component.

[0046] The transmission assembly includes a storage chamber 1 and a transmission pipe 10 connected to the storage chamber 1. The storage chamber 1 is used to store materials, and the transmission pipe 10 is used to transmit materials. The injection assembly is located below the transmission assembly. The injection assembly includes an injection chamber 2 and a rotating member rotatably arranged in the injection chamber 2. The transmission pipe 10 is used to connect the storage chamber 1 and the injection chamber 2. The injection chamber 2 is provided with an output port. The material in the storage chamber 1 is transmitted to the injection chamber 2 via the transmission pipe 10, and can be hit by the rotating member during the rotation process to be injected into the output port.

[0047] The material injection device provided by the present disclosure includes a transmission component and an injection component, wherein the transmission component is used to transmit the material to the injection component, and the injection component is used to inject the material into the vacuum chamber. Among them, the transmission pipe 10 transmits the material in the storage chamber 1 to the injection chamber 2, and hits the dripping material through the rotating member in the injection chamber 2, so that the material dripping in the transmission component is injected into the output port by high-speed hitting, so that the injection of the material is faster and more convenient. Compared with the existing injection method of charging with gas, this high-speed hitting injection method is more efficient, which greatly improves the efficiency of feeding, and the material under high-speed hitting can be more effectively deposited into the plasma core in the vacuum chamber; compared with the existing injection method of high-pressure gas driven projectiles, this injection method can realize the effective injection of materials only through the high-speed hitting of the rotating member, that is, no driving gas is needed in the injection process of the material, that is, this injection method does not have the problem that the driving gas enters the vacuum chamber with the material and affects the normal operation of the vacuum chamber.

[0048] In some embodiments, reference Figures 1 to 6As shown, the rotating member is a rotating rod 3 extending in the horizontal direction. The rotating rod 3 rotates in the horizontal direction in the injection chamber 2. The position of the output port corresponds to the end of the rotating rod 3. In this way, the rotating rod 3 hits the dripping material during the rotation process, thereby ensuring that the material can be directly ejected toward the output port after being hit to enter the vacuum chamber.

[0049] In actual application, the transmission pipe 10 can be arranged in the external area between the storage chamber 1 and the injection chamber 2, so as to connect the storage chamber 1 and the injection chamber 2; the transmission pipe 10 can also extend into the storage chamber 1 and the injection chamber 2 respectively, so that the material in the storage chamber 1 can be transmitted or dripped into the injection chamber 2.

[0050] Reference Figure 7 As shown, specifically, the transmission pipe 10 extends into the injection chamber 2, and the pipe mouth of the transmission pipe 10 is arranged toward the side of the rotating rod 3, and the dripping path of the material in the pipe mouth of the transmission pipe 10 and the rotation path of the rotating rod 3 have an overlapping point, thereby ensuring that the material can just contact the side of the rotating rotating rod 3 during the process of dripping from the pipe mouth, so that the material dripping from the transmission pipe 10 is hit by the side of the rotating rod 3 and successfully injected into the output port.

[0051] It should be noted that the above-mentioned specific shape and rotation direction of the rotating part are only an exemplary setting method. In actual application, the rotating part can also be set to other structures, for example, it can be set to a wind wheel with multiple blades. During the rotation of the wind wheel, the blades can continuously contact and hit the dripping material, and inject the material in the direction close to the output port; or it can also be set to multiple rotating plates. During the rotation process, the side surfaces of the multiple rotating plates can also hit the material to complete the injection of the material.

[0052] In some embodiments, reference Figures 1 to 6 As shown, the injection assembly includes a first driving mechanism, which is located below the injection chamber 2. The first driving mechanism is connected to the rotating rod 3 to drive the rotating rod 3 to rotate in the horizontal direction in the injection chamber 2. The rotating rod 3 is a square rod-shaped structure, the length of the rotating rod 3 is adapted to the internal space of the injection chamber 2, the middle part of the rotating rod 3 is connected to the first driving mechanism, and the rotation speed of the rotating rod 3 is matched with the dripping speed of the material, so that both ends of the rotating rod 3 along the length direction can hit the dripping material, and the middle position of the side (i.e., the longitudinal side) of the end of the rotating rod 3 is formed as a hitting area, so that during the rotation of the rotating rod 3, the hitting area at at least one end of the rotating rod 3 can hit the dripping material in the direction close to the output port, so that the injection process of the material has good repeatability and consistency.

[0053] Specifically, the length of the transmission tube 10 can be controlled to ensure that the falling speed of the material dripping into the rotating area of ​​the rotating rod 3 is 2-10m / s. As the rotation speed of the rotating rod 3 increases, the time window for the middle part of the rotating rod 3 to pass directly under the nozzle of the transmission tube 10 is shortened, and the dripping speed of the material is required to increase accordingly (if the falling speed of the material does not increase accordingly, the rotating rod 3 returns to the bottom of the nozzle earlier or faster, and the material just drips to the middle of the end of the rotating rod 3 at the previous speed).

[0054] In the specific operation process, different sizes of rotating rods 3 can be selected according to the different sizes of the injection chamber 2, and different lengths of transmission tubes 10 can be selected to cooperate with different rotating rods 3 to ensure that they can accurately hit the required position, so that the rotating rod 3 can continue to hit the dripping material during the rotation process, so that the material can be injected into the vacuum chamber at a speed of 50-120mm / s.

[0055] Alternatively, compared to the above embodiment, the length of the rotating rod 3 can also be set to only half of the length of the rotating rod 3 in the above embodiment, so that one end of the rotating rod 3 along the length direction is connected to the first driving mechanism, and the other end forms a striking area for striking the dripping material. In actual application, the rotating rod 3 can be rotated in a circular manner in the horizontal direction, or can be reciprocated relative to the position of the nozzle of the transmission pipe 10 to improve the striking efficiency of the rotating rod 3 for the material.

[0056] It should be noted that, in the actual application process, the orientation of the nozzle of the transmission tube 10 needs to be adjusted to ensure that the middle part of the side of the end of the rotating rod 3 forms a striking area, so that the dripping material just contacts the striking area during the rotation of the rotating rod 3, and it can be ensured that the dripping material can be hit into the output port by the striking areas at both ends of the rotating rod 3. Otherwise, when the rotating rod 3 rotates, if the dripping material contacts the upper edge of the rotating rod 3, the material will be ejected obliquely upward; if the dripping material contacts the lower edge of the rotating rod 3, the material will be ejected obliquely downward, resulting in the inability to accurately inject the material into the output port.

[0057] In some embodiments, reference Figure 2 As shown, the first driving mechanism includes a motor 41 , a first flange 42 and an extension shaft 43 .

[0058] Specifically, the motor 41 is located below the injection chamber 2, and the motor 41 is fixed on the motor mounting frame 411. The first flange 42 can be a magnetic fluid flange, which is arranged on the side of the injection chamber 2 facing the first driving mechanism, and the magnetic fluid flange is fixed on the injection chamber 2, which can provide 5×10 -6The vacuum environment of Pa satisfies the sealing of the injection chamber 2 and ensures that the overall working environment of the injection chamber 2 is in a vacuum state. The output shaft of the motor 41 is connected to the first flange 42 to drive the first flange 42 to rotate.

[0059] The extension shaft 43 is located in the injection chamber 2, one end of the extension shaft 43 is connected to the first flange 42, and the other end is connected to the rotating rod 3. The motor 41 drives the rotating rod 3 to rotate through the first flange 42 and the extension shaft 43, so that the rotating rod 3 rotates in the injection chamber 2 along the horizontal direction to achieve high-precision hitting of the dripping material. The first flange 42 has two functions, which can not only ensure the high sealing of the injection chamber 2, but also meet the transmission requirements of the rotating rod 3. The motor 41 can be a variable frequency motor. The speed of the motor 41 can be adjusted by the controller to adjust the speed of the rotating rod 3, so that the speed of the rotating rod 3 is adapted to the dripping speed of the material, ensuring that the material can be hit smoothly into the vacuum chamber.

[0060] In some embodiments, reference Figure 2 As shown, the first driving mechanism also includes a coupling 44, which is connected between the output shaft of the motor 41 and the first flange 42. The coupling 44 is used to compensate for the deviation between the output shaft of the motor 41 and the axis of the magnetic fluid flange, such as radial and axial deviations, to ensure the concentricity of the output shaft of the motor 41 and the axis of the magnetic fluid flange, so that the transmission between the two shafts can be more balanced and the driving process of the motor 41 is smoother.

[0061] In some embodiments, the transmission tube 10 is gradually narrowed in the direction from the storage chamber 1 to the injection chamber 2, that is, the transmission tube 10 has a funnel-shaped structure to better guide the material to drip to the target position, and can prevent the material from dripping randomly into the injection chamber 2. The inner diameter of the end of the transmission tube 10 close to the rotating rod 3 is 2mm-5mm, and the distance between the end of the transmission tube 10 close to the rotating rod 3 and the middle of the rotating rod 3 is 3mm-20mm. In other words, the inner diameter of the tube body at the lower end of the transmission tube 10 is 2mm-5mm, and the distance between the lower end of the transmission tube 10 and the rotating rod 3 is 3mm-20mm, so that the material can enter the injection chamber 2 according to a certain dripping direction and dripping speed.

[0062] In some embodiments, reference Figures 7 to 9As shown, the material injection device also includes a butt joint pipe 5, which is sleeved on the outer peripheral wall of the transmission pipe 10, and there is a gap between the inner peripheral wall of the butt joint pipe 5 and the outer peripheral wall of the transmission pipe 10, one end of the butt joint pipe 5 abuts against the side of the injection chamber 2 facing the storage chamber 1, and the other end abuts against the side of the storage chamber 1 facing the injection chamber 2. The butt joint pipe 5 can be a corrugated pipe or a pipe body structure of other plastic materials. Since the material dripping is mainly achieved by vibration in the transmission component, the butt joint pipe 5 is fixed to the transmission pipe 10 between the storage chamber 1 and the injection chamber 2. During the vibration of the storage chamber 1, the butt joint pipe 5 has a gap with the transmission pipe 10, so the butt joint pipe 5 itself can be slightly shaken relative to the storage chamber 1 and the injection chamber 2, thereby reducing the vibration of the storage chamber 1 during the vibration of the material dripping process caused to the injection chamber 2, and controlling the vibration between the storage chamber 1 and the injection chamber 2 within a reasonable range, preventing the vibration in the injection chamber 2 from being too large, affecting the injection of materials and the normal operation of the injection chamber 2.

[0063] In some embodiments, reference Figure 3 As shown, the output port is connected to an output pipe 20, and the struck material will be shot into the output pipe 20 and then enter the vacuum chamber. The material in the embodiment of the present disclosure is a granular structure, which is a solid projectile, i.e., a granular material, which is then injected into the plasma in the vacuum chamber at a high speed through an injection assembly to realize feeding, so as to control the plasma density time.

[0064] Furthermore, a guide tube 21 is provided in the output tube 20 for guiding out the granular material. The output port of the guide tube 21 is a rectangular hole. By adjusting the orientation position of the output port of the guide tube 21 in the output tube 20, the granular material can be injected into the vacuum chamber in a certain ejection direction. That is to say, the output port with a larger diameter is arranged toward the rotating member to better receive the material. The material is collected through the guide tube 21 and discharged from the port with a smaller diameter, so that the material, especially the granular material, can be added to the vacuum chamber to be added in a regular shape. In the actual application process, the output port of the guide tube 21 can be adaptively arranged according to the shape or size of the material required for the fusion reaction, so that the material that meets the required shape or size can be output through the output port of the guide tube 21, so that the guide tube 21 can not only adjust the ejection direction of the material, but also screen out the required material for the fusion reaction, thereby avoiding the problem that the irregular discharge of the granular material easily causes splashing, wastes the material and easily causes explosion. This allows the granular material to be injected into the plasma in the vacuum chamber more regularly, quantitatively and evenly during the injection process, thereby improving the boronization effect to a certain extent, thereby effectively improving the efficiency of the fusion reaction.

[0065] Moreover, the flow guide tube 21 not only guides the granular materials during the injection process, but also has the function of preliminary screening the granular materials. According to the specific needs of the plasma, the specific size of the output port of the flow guide tube 21 is adjusted so that only the granular materials that meet the preset particle size can be smoothly ejected from the output port of the flow guide tube 21, that is, the flow guide tube 21 only allows the granular materials that are smaller than the preset particle size to pass through, and the granular materials that are larger than the preset particle size will be blocked in the injection chamber 2 and cannot be ejected, thereby ensuring that the particle size of the granular materials injected into the vacuum chamber from the output tube 20 meets the requirements, avoiding negative impact on the plasma.

[0066] In some embodiments, reference Figures 7 to 9 As shown, the transmission component also includes a feed tank 12 and a feed member. A storage tank 11 is arranged above the feed tank 12, and the storage tank 11 and the feed tank 12 are connected to each other, and are used to transport the materials stored in the storage tank 11 to the feed tank 12. The storage tank 11 and the feed tank 12 are both located in the storage chamber 1, and the feed member is located below the feed tank 12, and is used to receive the materials transported by the feed tank 12. In addition, the length of the feed tank 12 is short, and there are fewer materials inside it, so the stacking pressure is small, which avoids the materials, especially the granular materials, from being over-pressured and causing blockage after the accumulation. During the application process, the materials in the transmission component can be of different particle sizes, shapes and materials, so the number and type of the storage tank 11 can be selected according to the different types of different materials. For example, two types of materials, borane and lithium alkane, can be selected, that is, there can be two groups of storage tanks 11 and feed tanks 12 connected in pairs. The volumes of the storage tank 11 and the feed tank 12 can be determined based on the injection volume of a single experiment to avoid opening the tanks and adding materials during the experiment to destroy the vacuum environment. While ensuring the volumes of the storage tank 11 and the feed tank 12, 2-7 storage tanks 11 and the feed tank 12 can be set.

[0067] In addition, the gap between the feed tank 12 and the transmission trough 6 is 1 mm, and the height between the two is adjustable within a range of 0.1 mm to 2 mm, in order to ensure that the material can be transferred from the adjustable gap to the transmission trough 6 and to control the material transfer amount. In other words, the larger the gap between the feed tank 12 and the transmission trough 6, the more material is transferred, and the smaller the gap between the feed tank 12 and the transmission trough 6, the less material is transferred.

[0068] The material delivery tank 12 is configured to deliver materials to the material delivery member under vibration, and the material delivery member is configured to transfer the received materials to the transmission pipe 10 during movement, thereby delivering the materials in the storage tank 11 to the transmission pipe 10, so as to be injected into the output port through the high-speed impact of the rotating part.

[0069] Specifically, refer to Figure 8 and Fig. 9As shown, the material feeding member includes a transmission groove 6 and a cover plate 61 covering the transmission groove 6, and the transmission groove 6 is extended in the horizontal direction. A feed port connected to the transmission groove 6 is provided on the cover plate 61, and the output end of the feed tank 12 extends into the feed port, so that the material in the feed tank 12 is transported to the transmission groove 6 through the feed port. The slot of the transmission groove 6 passes through the two ends of the transmission groove 6 along the length direction, and a discharge port 62 corresponding to the transmission pipe 10 is formed between the cover plate 61 and the end of the transmission groove 6, so that the material in the transmission groove 6 can be smoothly transported to the transmission pipe 10 through the discharge port 62. In the actual application process, the material feeding member can also be set as a funnel-shaped feed pipe, the upper end of the funnel-shaped feed pipe is connected to the feed tank 12, and the lower end is connected to the transmission pipe 10. When the feed tank 12 vibrates, the material inside falls into the funnel-shaped feed pipe under the action of gravity, and is transported to the transmission pipe 10 along the funnel-shaped feed pipe, thereby realizing the transmission of the material.

[0070] The transmission assembly also includes a vibration mechanism, which is located in the storage chamber 1. The vibration mechanism is connected to the transmission slot 6 so that the transmission slot 6 can drip the material into the transmission pipe 10 through the discharge port 62 under the action of vibration. Specifically, the vibration mechanism includes a drive motor and a piezoelectric driver 7. One end of the piezoelectric driver 7 is connected to the drive motor, and the other end is connected to the transmission slot 6. The piezoelectric driver 7 is set at a certain angle to the bottom of the transmission slot 6, for example, it can be set at 45°-90°. Specifically, the side of the storage chamber 1 is connected to the second flange 13, and the second flange 13 is a vacuum flange. The vacuum flange is connected to the external drive motor so that the interior of the storage chamber 1 is a vacuum environment. In addition, the vacuum flange can also provide driving force for the piezoelectric driver 7. The driving motor controls the vibration frequency of the piezoelectric driver 7 by adjusting the voltage drive of different frequencies. The piezoelectric driver 7 is used to vibrate in a direction parallel to the bottom of the transmission groove 6, so that the transmission groove 6 is repeatedly displaced along the length direction of the bottom of the groove, so that the material in the transmission groove 6 is shaken off into the transmission pipe 10 through the discharge port 62 under repeated vibration, thereby transmitting the material in the transmission component to the injection component, so that the transmission groove 6 is driven by the vibration mechanism to vibrate to a certain extent, which can realize the control of the material transmission rate and further improve the accuracy of material injection.

[0071] In a specific embodiment, the storage tank 11 is fixedly connected to a fixed horizontal plate provided in the storage chamber 1, and the delivery tank 12 is fixed to a third flange 14 provided at the bottom of the storage chamber 1. The piezoelectric driver 7 vibrates and drives the delivery tank 12 connected to the transmission trough 6 to repeatedly displace in the horizontal direction or in the horizontal and vertical directions at the same time, so that the storage tank 11 and the delivery tank 12 produce relative movement, and the storage tank 11 stirs the delivery tank 12 to prevent the material from being accumulated and blocked. In a preferred embodiment, the delivery tank 12 is a funnel-shaped structure, which can ensure that the material is quickly shaken off from the delivery tank 12 to the transmission trough 6.

[0072] In some embodiments, the transmission trough 6 is V-shaped along the length direction to better accommodate the dripping materials, and can guide the materials to a certain extent, so that the materials can be more guided into the discharge port 62 when vibrated. It should be noted that the transmission trough 6 should be arranged to extend in the horizontal direction in the storage chamber 1, so that the materials in the transmission trough 6 can be smoothly shaken into the transmission pipe 10 when the transmission trough 6 is vibrated, and when the vibration mechanism stops vibrating, the transmission trough 6 can stably maintain the horizontal state to prevent the materials in it from continuing to shake into the transmission pipe 10. In other words, the transmission trough 6 is arranged in the horizontal direction, so that when there is no need to transmit materials, the materials can be stably accommodated in the transmission trough 6, and when the vibration mechanism stops vibrating, the transmission trough 6 can also stop conveying materials synchronously. And according to the actual material transmission needs, the opening size between the side of the cover plate 61 and the notch can be flexibly adjusted, that is, the size of the discharge port 62 of the transmission trough 6 can be adjusted to control the transmission amount of the materials in the transmission assembly.

[0073] It should be noted that the above-mentioned transmission method of shaking the material in the transmission trough 6 into the transmission tube 10 by the vibration of the transmission trough 6 by the vibration mechanism is only an exemplary setting method. In the actual application process, the transmission method of the transmission component can be flexibly set according to different transmission requirements. For example, in other embodiments, the feeding member includes a driving member and a feeding screw connected to the driving member. The feeding screw is extended in the horizontal direction and is located below the feeding tank 12. The material in the feeding tank 12 falls to the gap of the external thread of the feeding screw under the action of gravity. The driving member drives the feeding screw to rotate in situ so that the material in the feeding screw drips into the transmission tube 10 as the feeding screw rotates. This material transmission method can also smoothly transmit the material in the transmission component to the injection component, and can avoid the situation that when the material is transmitted by vibration, multiple components will be affected by the vibration, causing vibration inside the entire component, thereby causing the transmission component and the injection component to lose control.

[0074] In some embodiments, reference Fig.10 As shown, the injection assembly also includes a fixing portion 22, which is used to fix the storage chamber 1 as a whole above the injection chamber 2, and a flange or a fixing bracket or the like can be used to ensure the overall stability of the storage chamber 1. The injection assembly also includes a mounting bracket 23, which is supported on the ground, and the injection assembly is fixed on the mounting bracket 23 as a whole to ensure the overall stability of the injection assembly and the transmission assembly, so that the entire process of transmitting and injecting materials can be more stable and reliable.

[0075] The present disclosure also provides a fusion reaction system, comprising the material injection device in any of the above embodiments.

[0076] The device can realize the simultaneous injection of different types of materials, and during the injection process, different types of materials are independently controllable. The material dripping in the transmission component can be injected into the output port on the injection component by high-speed striking, making the injection of materials faster and more convenient. Compared with the existing injection method, this high-speed striking injection method is more efficient, which greatly improves the feeding efficiency, and enables the material under high-speed striking to be more effectively deposited into the plasma core in the vacuum chamber. The effective injection of materials can be achieved only by the high-speed striking of the rotating part, that is, there is no need to use driving gas during the injection process of the material. In other words, this injection method does not have the problem of driving gas entering the vacuum chamber with the material and affecting the normal operation of the vacuum chamber.
